H747-Test

This is a mix between using CubeMX to create the project with AzureRTOS enabled on both cores and adding parts from the LCD_DSI_CmdMode_DoubleBuffer example for STM32H747I_DISCO

  • M4 will :

    1. toggle the orange LED twice per second using 1 tx thread
    2. write things on the UART once per second using 1 tx thread
    3. read data from I2C1 and put the retrieved data in shared memory for M7 using 1 tx thread
    4. read data from I2C4, same as above; this includes data from touch-screen interface circuit

  • M7 will : 0. setup LCD display through some calls to BSP before launching the tx threads

    1. toggle blue LED once per second; retrieve touch screen data from the shared memory and post PEN events for guix using 1 tx thread; toggle green LED on PEN_DOWN and PEN_UP events
    2. start guix using 1 tx thread and setup a timer to periodically update a displayed value obtained from the shared memory (I2C data sent by M4)

GUIX was added as a git submodule

The display is generated from GUIX Studio and the large font is also generated by GS from the Cascadia Code font available here : https://github.com/microsoft/cascadia-code/releases
